This invention relates tomimprovements in car construction. v

One object of the invention is to provide a combined center and locking pin for body and truck holsters of railway cars having eX- ceptionally great tensile strength, wherein the pinA has head members at opposite ends thereof .having shouldered engagement with the holsters along relatively large areas, the head members being `formed by sectional locking blocks embracing enlargements at opposite ends of the pin, one ofk which is of such' a size that it vwill pass through the pin receiving openings to facilitate application of the pinto the holsters and locking the same thereto.

A further object of the invention is to provide a combined locking and center pin of the character described in the preceding paragraph, wherein the shank is of smaller diameter than the pin receiving openings of the holsters, thereby permitting bodily displacement laterally of thefpin in assembling the locking blocks therewith, thereby allowing Ythe use of lockingfblocls having relatively Wide retaining shoulders cooperating with the enlargements of the pin and the shoulders of the holsters.

Other objects of the invention will more clearly appear from ythe .description and claims hereinafter following.

ln `the drawing, forming a part of this specification, Figure 1 is a top plan view of a portion of a body bolster of a railway car illustrating my improvements in connection therewith.' Figure 2 is a vertical, sectional view corresponding substantially to the line 2--2 of Figure 1. Figure 3 isa bottom plan view of the truck bolster illustrated in Figure 2, illustrating my improved pin in connection therewith. And Figure 4 is a detailed, perspective view of a locking vblock forming a part of tliesectional head at one end of the improved center pin.

ln said drawings, 10 designates the body bolster and 11 the truck holsterv of'a railway.y

car. The `body holstery is provided with a bearing projection 12 cooperating with a bearing seat provided on a block13 seated in a pocket 14'at the top of the truckbolster.

In" carrying out inyinvention, IV provide the body and truck holsters with alined center pin receiving openings 15 and 16 of substansponding diameter. The bearingphlock 13vi`s alsoprovided with a pin receiving opening 17 corresponding in cross section and size t0 `tially'cylindrical cross section and ofcorrei the openingsl and 16 of the body and truck Y holsters. The body 'bolster is provided with a pocket 18 at the outer end of the opening 15, the pocket also being of circular cross section but of larger diameter than the opening 15,

thereby providing an annular retaining shoulder 19a-t the inner end of said pocket.

The truck bolster is also provided with a pocket 20 whichis of circular cross section and is l'ocatedat the outer end of the ,pinreceiving opening 16 of said bolster. The pocket 20v'is of larger diameter than' the opening 16, thereby providing an "annular retaining shoulder 21 at theinner end of said pocket.

vMy' improved combined locking and centerpin comprises broadly a pin member A, a

sectionalhead B at each end of the'pin,'each I head comprising three locking blocks; and a pair ofretaining caps C-D cooperating with the sectional heads at opposite ends of the pin.

The pin member A has'a shank portion whichis of cylindrical cross section and of smaller diameter than the pin receiving openings 15 and 16 of the holsters, as clearly shown in Figure 2. At the top and bottom ends, the pin member A is provided with enlargements 22--22 which are in the `form of annular head members. VThe enlargements 22-221 areof" such a diameter that they will pass through the pin Vreceiving openingsof the bolsters`,'therehy facilitating assembling of l tlre'piri with the holsters. kAs will he evident,

the -pin may he assembled with the holstersvr by entering the 'same either through the opening offthebodyrholster or the-opening of the truck bolster, fthe heads 22 passing freely through thepin receiving openings 15 and 16;

`The `sectional heads vB-Bat opposite ends, ofthe pin arev of similar construction, except' as hereinafter pointed out. Each head'pref-4 erahly- :comprises three sections 23-23-23,

which are in the form of blocks. Y Eachsec tion has a vertical wall portion 24@ of cylindrical form, an inner flange 25 laterally projecting therefrom and an outer wall 26. The

laterally projectingflange Yportions 25 of theY three blocks-23 together forman annularflange surrounding the shank of the pin inwardly of the corresponding enlargement 22 end of the pin.` The sections-23 of the head B of the bottom end of the pin differ from the sections 23 at the upper end of the pin in that each section is provided with an upstand- Y ing-portionv 27 at the center thereof, the three upstanding portions 27-'-27-27 together forming an annular boss for a purpose hereinafter pointed out. The retaining cap C at the upper end of-the pin is in the form of a sleeve fitting between the sectional head B at lthe upper ends of the pin and the side wall ofthe pocket 18. The sleeve-'like member C embraces the three sections of the head B, thereby holding the samer locked to the enlargement 22 at that end of the pin. The sleeve C is provided with a bail member 28 by which the same may be manipulated.

The retaining cap at' the bottom end of the pin comprises an annular wall portion 29 which is interposed between the sectional head B at that end of the pin and the side wall of the pocket 20. The bottom wall of the cap D is provided with a central open ing 30 through which the boss on the sec tional head B projects, the opening being surrounded by an upstanding annular flange 8l. The projecting boss formed by the portions 27 of the sections 23 of the bottom head B and the annular wall 3l of the cap D are provided with alined openings adapted to receive a cotter` pin 32 by which the cap is secured to the sectional head.

Inasmuch as the shank of the pin member B is of smaller diameter than the Corresp onding pin receiving openings of the body and truck holsters, the pin member A is bodily displaceable laterally so as to facilitate Yassembling of the head members B with the pin. In this connectiomit ispointed out that the Width of the annular flanges formed by the flange sections 25--25 Vof-the bloclrs23 at each end of the pin overlap the annular shoulder formed by the corresponding enlargement22 and the inner faces of the blocks 23 overlap the annular retaining shoulder of the. corresponding bolster to such an extentthat the combined overlap of these parts is greater than the clearance between the enlargement and theside wall of the pocket of the corresponding bolster, thereby providing shouldered engagement on relatively wide areas. The employment of locking blocks 4of this design is made possible by providing holsteito permit insertion of the sect-ions of the head.

ln applying my improved center pin to the holsters of a railway car for connecting the same, the pin member A is applied by ing the same either upwardly1 through the truck bolster or downwardly through the body bolster, the corresponding enlargement 22 being passed through the pin receiving openings ofV the holsters. W hen the pin member A has been positioned as shown in Figure 2, the sectional heads are applied to opposite ends thereof. Each head is applied in the following manner: The pin member A is displaced to one side of the pin receiving openings of the holsters, thereby providing sufficient clearance between the enlargement 22 and the opposite side wall of the correvsponding head receiving pochetto allow passage of the flanged portion at the inner end of one of thefbloclrs 23. This block is then inserted and displaced laterally iniifardly to bring the flange 25 thereof beneath the shoulder of the corresponding head 22. The pin then vdisphnied laterally to permit the successive application of the remaining two blocks of the sectional head in a similar manner, sufficient lclearance being provided between the side face of the block 23 firstapplied, and the corresponding side wall poition of the* pocket of the corresponding bolster to permit the necessaryT displacement of the pin member A to allow insertion of Athe section at the other side of the pin.

After the two sectional heat s B-B have been applied the retaining members C and D are telescoped over the head members B and the retaining cap D is secured to the lower sectional head B by the cotter pin 32.

ln separating the bolster7 the pin is removed by a procedure substantially the reverse of the assembling operation, the two caps C- and D being first removed from the sectional heads and the pin member B then laterally displaced in proper directionsl to allow disengagement of the three sections 223 successively from the corresponding enlargement of the pinr member A. Then the sec` tional members B-B have been completely removed from the enlargements of theI pinr` the pin member A may be either withdrawn by lifting the` same upwardly through the body bolster, or by permitting the same to drop through the truck bolster.

l have hereinshown and described what l now consider the preferred manner of carry-- ingi-oiitmy invention, .but the same is merely illustrative andi contemplate all changes and modifications thatcome within the scope.r
